I found this 1977 nickel in some pocket change with no mint mark. I think it might be doubled die letters on the front and back, but wanted to get another opinion. Thank you!
I see no doubling. The correct terminology is just Doubled Die not Double Dyed.. No dye is used in the minting proccess.
Welcome to CT @toughfind. Not to add insult to injury, it is Nickel, not nickle. You have a nice example that is 43 years old, but I also see nothing special about it.
As stated lighting affects what we see. Also that could be Die Deterioration Doubling considered worthless doubling and nothing to do with a true Doubled Die variety.
Any doubling you see on this coin is NAV or no added value doubling. The correct term is Doubled Die. Welcome to CT.
